Notes: 1. Timing measurement references are 0.8V and 2.0V.
Input AC drive levels are 0.45V and 2.4V, unless
otherwise specified.
2. OE may be delayed up to t
CE
- t
OE
after the falling edge
of CE without impact on t

.
3. OE may be delayed up to t
ACC
- t

after the
address is valid without impact on t
ACC
.
4. This parameter is only sampled and is not 100% tested.
5. Output float is defined as the point when data is no longer
driven.
